The invention relates to shipbuilding, in particular, to a method for manufacturing a vessel hull bulk block and a device for carrying it out.

A known method of manufacturing a volumetric block of the hull of the ship, consisting in the preliminary manufacture of individual sections of the volumetric block and the assembly and welding of the block from these sections in the assembly and welding tilter 1.

A device for carrying out this method is known, comprising an assembly-welding tilter equipped with welding equipment and grippers for fixing sections 1.

The disadvantages of this method and device are the complexity of the assembly and the large labor intensity of manufacturing the hull block.

The purpose of the invention is to facilitate the assembly and reduce the complexity of manufacturing the vessel hull block.

This goal is achieved by the fact that according to the method, the formation of a volumetric block is carried out by successively feeding sections into the assembly-welding tilter and turning the tilter 90 ° before each new section is fed into it.

To implement this method, the device is equipped with an installation roller, mounted under the base of the turner and interacting with it, and the installation live bed is equipped with retractable pressure beams, and the grips of the turner are installed along the perimeter of its paivibi.

FIG. 1 shows a device for making a vessel hull volume block; in fig. 2 - device feeding and installation roller tables; in fig. 3 - assembly and welding tilter; in fig. 4 shows the operation of feeding the bottom section; in fig. 5 shows the installation of the bottom section; in fig. 6 shows a transverse bulkhead feeding operation; in fig. 7 shows a longitudinal bulkhead installation operation; in fig. 8 shows the installation of the upper deck section; in fig. 9 shows the installation of the on-board section; in fig. 10-operation of the block reversal to the normal position.

The device contains a feed and a receiving roller table 1, between which is located the installation roller table 2, mounted under the base of the assembly and welding tilter 3 and interacting with it.

Rollers 4 are installed on roller tables 1, on which sections of the vessel are moved. The installation roller 2 is equipped with sliding rollers 5 D / 1H longitudinal movement and sliding rollers 6 for lateral and circular movement of the sections and the block.

At the base of the roller table 2 recessed racks are recessed - jacks 7, on which transverse supports 8 are mounted.

Along the perimeter of the frame of the collar 3, the grippers are installed.

The bottom section 9 of the volume unit is placed by a crane on the feed roller table 1 and is moved along the rollers 4 to the installation roller table 2, where it is moved along the sliding rollers 5 and 6 and turned into the desired position. After that, the rollers 5 and 6 lower, and the rack - jacks 7 with transverse support beams 8

Section 9 is extended and lifted to the position it occupies in the bulk block and fixed with clamps - locks O of the assembly and welding tilter 3. Then the crane serves the section 11 transverse bulkhead, is installed and welded to the bottom section 9 in the lower position.

Then, the assembly-welding tilter 3 is turned 90 ° to the position for installation of the section 12 of the longitudinal bulkhead, which is also placed on the feed roller 1 with a crane and the process is repeated. In this case, when the section 12 of the longitudinal bulkhead on the sliding racks - jacks 7 to the supporting beams 8 is fed from the bottom up to the position 5G, which it occupies

in the bulk of the ship hull block, the retainers 10 secure the section in the assembly and welding tilter 3, and the longitudinal bulkhead section 12 is hooked to the bottom section 9 and to the transverse bulkhead section 11. Then, the longitudinal bulkhead 12 is welded to the bottom 9 and the transverse bulkhead 11. All assembly and welding work is performed in the lower position. Assembly-welding tilter 3 is rotated 90 ° to the position for mounting the section of the upper deck 13 and the process is repeated.

In this case, the assembly and welding work on the section of the upper deck 13 with the longitudinal bulkhead 12 and the transverse bulkhead 11 is performed in the lower position.

Then, the assembly-welding tilter 3 is rotated 90 ° to the position for mounting the bead section 14 of the vessel hull bulk block and the process is repeated. In this case, the assembly and welding work on the side section 14 with the bottom section 9, the transverse bulkhead 11 and the longitudinal bulkhead 12 is performed in the lower position. Then, the assembly-welding tilter 3 is rotated by 90 °, the formed volume block of the ship hull

is in a normal position, i.e. the bottom 9 at the bottom and the upper deck 13 at the top, push the rack - jacks 7 with support beams 8, and the assembled and welded surround unit is released from the clamps 10 and transplanted to the rollers 5

installation roller table 2, which is moved to the feed roller table 1, from where it is transported for further construction of the vessel.
